Most of the time, though, project developers walk up to those that might help and say, “I have a glimmer of an idea, will you help me?”

The challenge: It’s too challenging. Open-ended. To offer to help means to take on too much. And of course people are hesitant to sign on for an unlimited obligation to help with something that’s important to you, not to them.

Consider the bingo method instead.

Build a 5 x 5 grid. 25 squares. Twenty-five elements that have to be present for your project to have a chance. If it’s a fundraising concert, one of the grids might be, “find a theater that will host us for less than $1,000.”

Here’s the key: Fill in most of the grids before you ask someone for generous help. When nine or twelve of the squares are marked, “done,” and when another six are marked, “in process,” then the ask is a lot smaller.

A glimpse at your bingo card indicates that you understand the problem, that you’ve highlighted the difficult parts and that you’ve found the resources and the knowledge necessary to complete most of it.
